Communicating with symbols
The flattened areas on these hematite (left) and limonite (right) pieces of pigment are signs of grinding or rubbing, telling us that they were held and used like chunky crayons. With pigments, our ancestors marked objects and possibly their own skin. Colors were symbols by which they identified themselves and their group.
